When one of the two or more power supply and distribution circuits supplying power simultaneously experiences a disruption, the remaining circuits should be able to meet the power demand for ( ). A. All first-class loads B. Some first-class loads C. All first-class loads and second-class loads D. All first-class loads and those among the first-class loads that are particularly important
It should be all the first-class loads and those particularly important among the second-class loads; the last answer seems a bit problematic.
All first-class loads include those that are particularly important among the first-class loads; why is it necessary to repeat them?
Yes, I have an epiphany. Hehe. . . . .
C. All primary loads and secondary loads
D. All first-class loads and those that are particularly important among the first-class loads
When power supply to one of two or more power supply and distribution circuits operating simultaneously is interrupted, the remaining circuits should be able to meet the power demand specified in (c). C. All primary loads and secondary loads
When one of the two or more power supply and distribution circuits supplying power simultaneously experiences a disruption, the remaining circuits should be able to meet the power demand for ( ). D. All first-class loads and those that are particularly important among the first-class loads
When one of the two or more power supply and distribution circuits supplying power simultaneously loses power, the remaining circuits should be able to meet the power demand for (C).
